Antonio KAWALKOWSKI (1910-_____) NY, ID, OR

Antonio KAWALKOWSKI may have changed his name to Tony KAY. He was born in NY in 1910. He had a sister, Margaret, who was born in ID about 1915. He is/was my great uncle and I am looking for him or his descendants who may have information about his parents Frank KAWALKOWSKI and Stella (nee WIDZINSKA, formerly BLECK) KAWALKOWSKI. I’m hoping to track down descendants.
